How the world has changed! Plasma screens, Facebook, iPods—and, of course, cameraphones. Radar is a free application that allows you to send pics from cameraphone to cameraphone. All you have to do is sign up, free of charge. So if you happen to have held up your cameraphone at the exact moment that Craig did that crazy thing he didn’t want you to share with anyone, well, with Radar’s technology at your fingertips, you may have trouble keeping the secret. You can share the picture, post it, and talk about it with your friends, all using your phone—you don’t even have to be near a computer. It’s not artsy photography; it’s not going to get you a show in a gallery; but it’s real. Radar is the reason the cameraphone was invented.
